220V 1.8 Degree Brake Stepper Motor NEMA23
Product description
- 1. Longer Life
- Stepping motor is a mechanical structure,which does not need be
changed by electric brush or Hall sensor,thus reducing the
probability and increasing the motor life.Stepping motor life
usually determined by the life of the bearing.
- 2.Material quality: The coat is 304 stainless steel, the water
jacket is the high compression casting aluminum tube, the red
copper coil.
- 3. Accurate Speed Control
- The rotational speed of the stepping motor can be precisely
controlled ,By controlling the frequency of the electric pulse.

Speed/Torque Characteristics(Reference Value)
Operation of Stepper Motor:
Stepper motors operate differently from DC brush motors, which rotate when voltage is applied to their terminals. Stepper
motors, on the other hand, effectively have multiple toothed
electromagnets arranged around a central gear-shaped piece of iron.
The electromagnets are energized by an external control circuit,
for example, a microcontroller.
Applications of Stepper Motors
s
Computer controlled stepper motors are a type of motion-control
positioning system. They are typically digitally controlled as part
of an open loop system for use in holding or positioning
applications.
In the field of lasers and optics they are frequently used in
precision positioning equipment such as linear actuators, linear
stages, rotation stages, goniometers, and mirror mounts. Other uses
are in packaging machinery, and positioning of valve pilot stages
for fluid control systems.
Commercially, stepper motors are used in floppy disk drives,
flatbed scanners, computer printers, plotters, slot machines, image
scanners, compact disc drives, intelligent lighting, camera lenses,
CNC machines and, more recently, in 3D printers.
